Description

Technical Field

[0001] This application belongs to the field of air conditioning systems and equipment, and more specifically, relates to a ceiling-mounted integrated air conditioning unit. Background Technology

[0002] For large spaces such as subway platforms, ventilation is required to remove air pollutants. Therefore, air supply vents are installed above the platform ceiling to supply air to the platform and exhaust vents to discharge the supplied air pollutants to the outside of the platform. For example, Chinese Patent Publication No. CN112833495A discloses a ventilation system for a subway platform, specifically disclosing the following technical solution: It includes an air supply duct through which air supplied to the subway platform flows; an exhaust duct through which air drawn in from the subway platform flows; multiple air supply hoods that discharge the air flowing in the air supply duct into the interior of the platform, and are spaced apart from each other in the direction of air flow in the air supply duct; and multiple exhaust hoods that allow air supplied to the interior of the platform through the air supply hoods to be drawn in along with pollutants present in the platform, and are spaced apart from each other in the direction of air flow in the exhaust ducts. The air supply hoods are configured to supply air at a predetermined angle downwards towards one side surface of the platform.

[0003] However, in the relatively large spaces of subway platforms, air conditioning systems are necessary to regulate temperature and humidity. For example, Chinese Patent Publication No. CN106152349A discloses a subway station ventilation and air conditioning environmental control system, specifically outlining the following technical solution: It includes a heat dissipation device, an air conditioning unit, and a compressor unit. These components form a refrigerant circulation loop via pipelines. The heat dissipation device is located at the subway station entrance / exit, and the air conditioning unit is located within the subway station space. This application utilizes the entrance / exit for fresh air replenishment; by installing heat dissipation devices at the entrance / exit, the heat and humidity load of the various systems within the subway station is exhausted to the outside atmosphere, eliminating the need for cooling towers as in traditional subway station ventilation and air conditioning environmental control systems; and by installing air conditioning units and compressor units within the subway station space, the space is cooled and dehumidified to meet passenger comfort requirements.

[0004] However, the shortcomings of the prior art, represented by patent document CN106152349A, are quite obvious, mainly in that "the heat dissipation device is set at the entrance and exit of the subway station, and the air conditioning unit is set in the space inside the subway station". This kind of split air conditioning device makes the pipeline layout in the subway station platform area more complicated, and the cost and installation difficulty are higher. The split air conditioning cannot be effectively coordinated with the existing ventilation system. Summary of the Invention

[0005] The purpose of this application is to provide a ceiling-mounted integrated air conditioning unit that can be installed in relatively open areas such as subway platforms and factory workshops, reducing installation difficulties caused by pipeline layout and other issues. It can also cooperate with the exhaust system in the open area to realize the exhaust of the outdoor unit's air force and reduce the impact on the interior space of the open area.

The outdoor unit housing 1 has several outdoor unit air inlets 4 on its circumferential side walls. The outdoor unit top shell 16 of the outdoor unit housing 1 has an outdoor unit air outlet 5 at its center. The bottom of the outdoor unit housing 1 has an outdoor unit bottom shell 13. The indoor unit housing 2 has an indoor unit top shell 14 at its top, which serves as a mounting point for the outdoor unit bottom shell 13. The bottom of the indoor unit housing 2 is integrally provided with a fixed base plate 3. The fixed base plate 3 has an indoor unit air inlet 10 at its center. An indoor unit air outlet 17 is provided on the fixed base plate 3 at a circumferential position of the indoor unit air inlet 10. An air guide plate is provided at the indoor unit air outlet 17. The circumferential edge of the fixed base plate 3 extends beyond the bottom edge of the indoor unit housing 2, forming a platform structure. The outer casing 1 is provided with an outer casing locking member 7 on its circumferential outer wall, and the inner casing 2 is provided with an inner casing locking member 9 on its circumferential outer wall. The inner casing locking member 9 is located at the junction of the inner casing 2 and the fixed base plate 3 and is fixedly connected to the inner casing 2 and the fixed base plate 3. A casing locking rod 8 is also fixedly provided on the fixed base plate 3. The casing locking rod 8 passes through the inner casing locking member 9 and the outer casing locking member 7 and is connected by fasteners.

[0024] Example 2

[0025] like Figures 1 to 4As shown, in this ceiling-mounted integrated air conditioning unit, a compressor assembly 12 is installed inside the outdoor unit casing 1, located on the bottom casing 13. The compressor assembly 12 is connected to the condenser 6 via a high-pressure steam pipeline and to the evaporator assembly 15 via a low-pressure steam pipeline. An axial fan is also installed inside the outdoor unit casing 1, which can exhaust the gas inside the outdoor unit casing 1 through the outdoor unit air outlet 5. A filter screen is installed at the outdoor unit air outlet 5. The condenser 6 is connected to the evaporator assembly 15 via a high-pressure gauge, capillary tube, and low-pressure liquid pipeline. A low-pressure gauge for measuring the pressure of the low-pressure steam pipeline is installed at the compressor assembly 12. An air supply fan assembly 11 is installed inside the indoor unit casing 2, located above the indoor unit air inlet 10. The evaporator assembly 15 is arranged around the air supply fan assembly 11, between the indoor unit air inlet 10 and the indoor unit air outlet 17. The compressor assembly 12 is provided with a condenser 6 in the circumferential direction.

[0026] The structure and connection relationships of the remaining parts are the same as those described in the foregoing embodiments.

[0027] Example 3

[0028] like Figures 1 to 4 As shown, in a ceiling-mounted integrated air conditioning unit, the outdoor unit housing locking component 7 and the indoor unit housing locking component 9 are located at the corners of the outdoor unit housing 1 and the indoor unit housing 2, respectively. The outdoor unit housing locking component 7 is an L-shaped plate, and the indoor unit housing locking component 9 is a horizontally placed U-shaped plate. The outdoor unit housing locking component 7 and the indoor unit housing locking component 9 have notches for housing locking rods 8 to be placed. The bottom end of the housing locking rod 8 is fixedly connected to the indoor unit housing locking component 9. The housing locking rod 8 has a threaded section and is connected to the outdoor unit housing locking component 7 and the indoor unit housing locking component 9 by fastening nuts. A filter screen is provided at the location of the outdoor unit air inlet 4 and / or the outdoor unit air outlet 5.

[0029] The structure and connection relationships of the remaining parts are the same as those described in the foregoing embodiments.

[0030] Based on the above embodiments, the following paragraphs will continue to describe in detail the technical features involved and the functions and roles of these technical features in this technical solution, so as to help those skilled in the art to fully understand the technical solution and reproduce it.

[0031] Traditional air conditioners consist of an indoor unit and an outdoor unit. The indoor unit includes a fan assembly 11 for supplying air to the room. The fan assembly 11 draws in indoor air and delivers it after passing through the evaporator. The evaporator is connected to a compressor assembly 12 via a low-pressure steam line, on which a low-pressure gauge is installed for pressure measurement. The compressor assembly 12 is also connected to a condenser 6 via a high-pressure steam line. The condenser 6 dissipates heat under the action of an axial fan assembly. The condenser 6 is connected to the evaporator via a high-pressure liquid line, a capillary tube, and a low-pressure liquid line. A high-pressure gauge is installed on the high-pressure liquid line.

[0032] In the aforementioned traditional air conditioners, since the indoor and outdoor units are separate, it is necessary to connect circulation pipes, such as low-pressure steam pipes and low-pressure liquid pipes. The lengths of these pipes vary depending on the spatial distance.

[0033] In open spaces, such as subway waiting areas, transfer areas, and other densely populated areas, as well as factory workshops, there are usually pre-installed ventilation systems. These systems allow air to be expelled from these open areas, achieving air circulation. However, in these relatively open spaces, traditional air conditioners, especially split-type air conditioners, require careful planning and installation of the indoor and outdoor units and their piping. Different placements of the indoor and outdoor units result in varying installation difficulties for the piping, making it impossible to reduce installation costs.

[0034] Therefore, in the aforementioned subway and factory workshops, in order to achieve integration with the existing ventilation system and reduce the installation cost of air conditioning, it is necessary to design an integrated air conditioning system that integrates the indoor and outdoor units and coordinates the exhaust air of the outdoor unit with the ventilation system to reduce the impact of the outdoor unit's exhaust air on the surrounding environment.

[0035] Therefore, the term "ceiling-type" used in this application is a series name used by the applicant and has no specific meaning. The outer casing 1 and inner casing 2 described in this application are stacked. The bottom shell 13 of the outer casing 1 is integrally formed at the bottom, and the top shell 14 of the inner casing 2 is stacked on top of it. Shock-absorbing pads can be provided at the stacking position, and these pads can be evenly distributed on the bottom shell 13 and the top shell 14 to reduce the mutual influence between the outer casing 1 and the inner casing 2. The outer casing 1 is provided with an outer casing locking component 7, and the inner casing 2 is provided with an inner casing locking component 9 corresponding to the outer casing locking component 7. The outer casing locking component 7 and the inner casing locking component 9 are connected by a casing locking rod 8 and fasteners. The bottom end of the casing locking component 8 is fixed integrally with the fixed base plate 3, allowing for overall hoisting via the casing locking component 8. Furthermore, the outer casing locking member 7 can be an L-shaped plate, fixed integrally with the outer casing 1; the inner casing locking member 9 is a U-shaped plate. Both the outer casing locking member 7 and the inner casing locking member 9 are machined with notches for placing and passing through the casing locking rod 8. These notches can be used to connect the outer casing locking member 7 and the inner casing locking member 9 to the casing locking rod 8 through nuts, buckles, or other structures. Due to the limited size of the drawing, the length of the casing locking rod 8 in the attached drawing is for illustrative purposes only.

[0036] In this application, the outdoor unit housing 1 is used to place and install the compressor assembly 12. A condenser 6 is installed inside the outdoor unit housing 1 by fasteners in the space around the compressor assembly 12. Air entering the outdoor unit housing 1 through the outdoor unit air inlet 4 can enter the outdoor unit housing 1 after passing through the condenser 6, and the air inside the outdoor unit housing 1 is sent out under the action of the axial fan assembly.

[0037] In this application, an air supply fan assembly 11 is installed inside the indoor unit housing 2. This air supply fan assembly 11 enables indoor air supply and, during the air supply process, can contact the evaporator assembly 15 inside the indoor unit housing 2 to exchange heat. The air supply fan assembly 11 is a vortex fan. During operation, it draws in air through the indoor unit air inlet 10. The drawn-in air is filtered by a pre-filter at this location to remove suspended particles before being sent to the evaporator assembly 15. After heat exchange in the evaporator assembly 15, the air is discharged from the indoor unit air outlet 17. The indoor unit air outlet 17 is located circumferentially around the indoor unit air inlet 10. A guide vane is installed at the indoor unit air outlet 17 to adjust the airflow spray angle. The airflow becomes turbulent and uniform after passing through the indoor unit air outlet 17 and the guide vane. The opening angle of the guide vane is controlled by a connecting rod and a drive motor.

[0038] In this application, the fixed base plate 3 is integrally set with the inner unit housing 2, which can not only support the inner unit housing 2 and the outer unit housing 1, but also enable the whole unit to be installed in the installation position.

[0039] In this application, the pipelines connected to the evaporator assembly 15, condenser 6, and compressor assembly 12, including high-pressure steam pipelines, low-pressure steam pipelines, high-pressure liquid pipelines, capillary tubes, and low-pressure liquid pipelines, are all arranged on the outer casing 1 and the inner casing 2, which can effectively reduce the difficulty and length of the above pipelines and reduce the overall installation difficulty.

[0040] In this application, the outdoor unit air outlet 5 is located above the outdoor unit housing 1. The air in the outdoor unit housing 1 will be discharged upwards by the action of the axial flow fan. In relatively open spaces such as subways and factory workshops, the upper part is mostly the exhaust system duct. The air discharged upwards by the outdoor unit air outlet 5 can be sent out through the exhaust system inlet and exhaust duct, thereby reducing the impact on open environments such as subways and factory workshops.

[0041] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
